J.H.Maiden, Forest Fl. New South Wales 6(10): 272–277, pl. 227 (1917), discussed the confusion surrounding the name A. cyperophylla . See also B.R.Maslin, W. Austral. Naturalist 18: 185–186 (1991). Acacia cyperophylla is related to an undescribed taxon of uncertain rank from the Pilbara region which is noted under A. rhodophloia , and is also related to A. grasbyi which is most readily distinguished by its shorter, nonpungent phyllodes.
